Hey All,

Having struggled quite a bit with getting video working on the
external video of the pismo, I have been wondering a lot about all the
different video drivers and what their relation is to one another.

If someone in the know could give a brief description, or point me to
some docs about the video kernel drivers and what relation they have
to the XF86 video drivers, I'd be more enlightened.

Things like "Option" "UseFBDev" confuse the heck out of me...

Thanks,
jas.
